Subject: Deprecate AV::RecordIdentifier in controllers

Methods provided by RecordIdentifier are not widely used in controllers
nowadays as they're view specific (this is probably a legacy left after
RJS rendering directly in controllers). However if people still need to
use it, it's trivial to include ActionView::RecordIdentifier by
themselves.
